Showing off her newly-purple ombre hair, the pop star jokes around with pals in the video, dancing and singing to Carly Rae Jepsen's viral hit. Her video is hilariously similar to the one made by Bieber and pals -- which has more than 33 million views on YouTube. Halfway through, Perry even takes the camera and starts calling out direction, showing that she is more-than-familiar with Bieber's version.
There are slick dance movies, iPhones and inflatable monkeys in Perry's poolside cover, which found its way online thanks to one of her friends. At the end, following a chorus of "Coachella!" cheers, Perry takes the camera and croons, "We love you Justin Bieber!"
